At least, it may help you to understand how the quadratic formula was derived.

Explanation:

I have to say that there was a time in high school that I had the same thought. I later came to understand that mathematics is not simply remembering and applying formulae but, rather, questioning how and why these formulae came to be - and so much more besides.

Have faith - It's worth it!!
